'To all whom, t may concern;

Be it known that I, ALBERT DE LAsxr, .a citizen of the United -States, and a resident of Trenton, in the county of Mercer and State o f New Jersey, have invented a new and useful Im rovement in Vehicle-Tires, of which the fo owing is as eciiication.

My invention re ates to vehicle-tires with, the object in view'of reventing the rolling 1o of the tire longitudinally when under heavy strain-as, for instance, on the driving-wheels of vehicles.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a view of the completed tire in cross-section,l representing the inner tube and the clencher-ring in dotted lines. Fig. 2 is a view of a portion of the tire in side ele- 2o vation broken away to show the different layers com rising it. Fig. 3' is a view in side elevation ofpart of the mandrel on which the restraining-jacket is formed, showing the restraining-j acket partially broken away. Fig.

4 is a transverse section through the same,

showing the restraining-jacket severed and partially removed from the mandrel; and

igs. 5, 6, 7, and 8 represent views corresponding with Figs. 1, 2,3, and 4 of a modi- 3o fied construction of the. restraining-jacket.

Referring to the form of restraining-jacket shown in Figs. 1 to 4, inclusive, the tire is composed of a circular-Woven fabric 1, having its opposite edges develo ed into shape, as

3 5 shown at 2 and 3, for eing held by the clencher-ring.

While the circular-woven fabric forms an exceedingly strong and durable body under all radial strains, it has been found important 4o Where a tire is subjected to great frictional strainjn longitudinal direction to reinforce this heavy circular-woven body by the application thereto of a jacket composed of threads disposed obliquely with respect to the longitudinal axis of the tire in order to exert a restraining pull more or less in a direction o posite that in which the tire is acted upon the frictional strain exerted upon.

it by the surface with which it is in contact.

l5o To this end I form upon a mandrel 4, preferably circular in cross-section, a jacket composed of a layer of threads 5 and a layer of soft rubber 6. The threads 5 may be braid.- ed directly onto the mandrel, as shown in Figs. 1 to 4, or they may be wound on the mandrel, one course obliquely in one direction and the other course obliquely inthe opposite direction, as shown in Figs. 5 to 8, inclusive, where the wound threads are indicated by 7. In both instances, however, there is one course of threads extending obliquely in lone direction and another course of threads extending obliquely in the opposite direction, so as to produce a restraining pull whether the wheel on which the tire is placed be driven forwardly or backwardly. On the layer of threads 5 or 7 I. apply a thin Patented Dec. 5,l 1905.VV

layer of soft rubber 6, pressing it closely into engagement with the layer of threads 5, and this having been done I cut the acket longitudinally along a shallow groove 8, formed in the mandrel, and then apply it to the circularwoven fabric 1 withthe layer 6 adjacent to the circular-woven fabric 1 and the layer of Woven threads 5 exterior. It is intended to make the restraining-jacket composed of the layers 5 and 6 of such extent transversely that it will extend. down more or less around the clencher ends 2 and 3 of the .circularwoven fabric, so that the clencher-hooks on ythe rim will overlap it in order to hold the edges of the restraining-j acket firmly clamped between the hooks on the clencher-ring and the clencher ends 2 and 3 of the circularwoven fabric. Exterior to the restrainingjacket thus formed I mold the tread 9 of the tire in any Well-known or approved manner and vulcanize the Whole together. When this vulcanizing process is completed, it will be found that the soft-rubber layer 6 has become intimately interlocked with the exterior of the circular-woven fabric 1 and the exterior of the 'thread layer of the restrainin jacket, so that the threads of the jacket 5 w' l be held securely in position, and the jacket so formed, While increasing the thickness of the tire but very little, will exert a very powerful restraining influence against the rolling of the body of the tire and will cause it to withstand without injury the great strains which are commonly imposed uponit in use.

While I prefer to braid the threads as shown in Figs. 1 to 4, I have found that when IOO and held in position by the soft layer of rubber they Will still exert a fairly satisfactory restraining influence.

braided threads, a layer of soft rubber interposed between the said braided threads and eiroular-woven fabric and a rubber tread applied on the braided threads, the whole being vulcanized into a coherent inass.
